Here's an idea.If you usually host those kinds of games on a local server, try downloading Rayman's Admin System off the workshop. Your other fellas don't need to download it in order for it to work, as it is loaded in with the server. The admin mod allows for countless fun things and virtually anything that sv_cheats can do including infinite ammo and even fort building, but here's the best part: it doesn't activate sv_cheats!This means you can still get achievements and stat progress while you mess around :) Hope this helps!
